Randomly connects to servers??? What kind of an app is this? It sounds liek you're trying to trick the software into connecting to a specific server because it's a trial version.
Depending on how the app is getting the server names and resolving them, you may not have any options to solve this. What is this utility and what kind of servers is it used for?

The only way to do what you want is to write your own proxy server. Your game would have to connect to the proxy server where all packets outgoing to the list of servers that you have would have to be re-written to be redirected to the new address. This is, by far, not an easy task.

You have to wait for the process to completely start before you send keystrokes to it. Instead of using Shell, you might want to use Process.Start instead. This will give you more options, like being able to check if the process has actually started yet.

Hi, can anyone tell me how can I set/revoke the permission to a folder for user in windows using VB.net.Thank you.

There's no support for this in the .NET BCL until the .NET Framework 2.0 comes out. You might want to checkout this[^] sample on GotDotNet.com.

Hi, i need to save to a text file with a variable name. This is what i have at them moment. It saves to mood.txt in the same directory as the project.
FileNum4 = FreeFile<br />
' Create mood.txt<br />
Open appPath & "mood.txt" For Append As #FileNum4<br />
' Write the contents of TextBox1 to mood.txt<br />
Print #FileNum4, mood; " , "; lblTime; " , "; songTitle<br />
' Close the file<br />
Close FileNum4
What i want tho, is for the filename to be "songTitle" mood.txt where songTitle is a varible As String. Ive tried this:
Open appPath & songTitle & " mood.txt" For Append As #FileNum4
But i get a bad file name error when i try to save to the file. Im sure there must be a way to do this, i just cant figure it out. How is it done?
Thanks

If you're going to have spaces in your filename, the entire file path must be enclosed in quotes: "C:\Documents and Settings\...."
Dim filePath As String
filePath = """" & appPath & songTitle & " mood.txt""" For Append As #FileNum4

Hi there,
May I ask a question?
I wanna write a program about Call Logs.
However, when researching the information about Call Logs in MSDN, I cannot find anything about that.
Would you please supply me any simple sample about Call Logs?
Thank you very much.

Perhaps MSDN, like me, has no idea what you mean by call logs ?

In smartphone SDK,it's include in "phone.h".

I need any simple sample or idea about Call Logs with vb.net or embedded vc++ 4.0 .
Would you please supply me any simple sample or idea about this?
Thank you~

How can i make a data grid in VB.Net
|
|
|
|
|
Do you want to elaborate on that? All you really need to do is drop a DataGrid control on your form. Afte that, it's up to you to supply the data, however you want, from wherever you want. So what's the real question here?

Hello,
I currently have a problem that i have thought of a soultion for but im unsure of how i can implement this.
Problem:
I have an new instance of a class, lets call it "Temp_Class" and within that class there are some properties x,y,z and say 6 instances of another class "Sub_Class". There may be 1 instance of "Sub_Class" or as many as 100 depending on Property X which is an integer.
Just like the "Temp_Class", "Sub_Class" contains some Properties A,B,C and up to 5 instance of a thrid class "Sub_Sub_Class" which just contains properties D,E,F.
I wanted to be able to referance each of the "Sub_Sub_Class" properties by using arrays so that i can set a varing amount of Sub_Classes or Sub_Sub_Classes where nessercary but for this i would need to create a new instance of each class. The problem with defining an array as a class is that it wont allow me to define it as a new class for some reason.
Public Temp_Class<br />
<br />
Private X_Value<br />
Private Y_Value<br />
Private Z_Value<br />
<br />
Public Property X .............(Get and Set are tested and are known to work)<br />
Public Property Y .............<br />
Public Property Z .............<br />
<br />
Public Array_1(X_Value) as Sub_Class<br />
<br />
End Class<br />
<br />
Public Sub_Class<br />
<br />
Private A_Value<br />
Private B_Value<br />
Private C_Value<br />
<br />
Public Property A .............<br />
Public Property B .............<br />
Public Property C .............<br />
<br />
Public Array_2(Y_Value) as Sub_Sub_Class<br />
<br />
End Class<br />
<br />
Public Sub_Sub_Class<br />
<br />
Private D_Value<br />
Private E_Value<br />
Private F_Value<br />
<br />
Public Property D .............<br />
Public Property E .............<br />
Public Property F .............<br />
<br />
End Class
The Idea is that you can then Referance any D,E,F propery as follows.
<br />
Dim Test as new Temp_Class<br />
<br />
Test.Sub_Class(0).Sub_Sub_Class(0).D = "Hello" '(assuming 'D' is a String)<br />
Test.Sub_Class(0).Sub_Sub_Class(1).D = "Test"<br />
Test.Sub_Class(0).Sub_Sub_Class(2).D = "Hello"<br />
Test.Sub_Class(0).Sub_Sub_Class(3).D = "Test"<br />
<br />
Test.Sub_Class(1).Sub_Sub_Class(0).D = "Hello"<br />
Test.Sub_Class(1).Sub_Sub_Class(1).D = "Test"<br />
Test.Sub_Class(2).Sub_Sub_Class(2).D = "Hello"<br />
Test.Sub_Class(2).Sub_Sub_Class(3).D = "Test"
I have been able to get this working but only if dont use arrays, but then everything becomes alot more complicated.
i.e. (tested and works, where items have been defined as new instances)
Test.Sub_Class_0.Sub_Sub_Class_0.D = "Hello"<br />
Test.Sub_Class_0.Sub_Sub_Class_1.D = "Test"<br />
Test.Sub_Class_1.Sub_Sub_Class_0.D = "Hello"<br />
Test.Sub_Class_1.Sub_Sub_Class_1.D = "Test"
If anyone can help me with this problem or if they know if this idea would even work it would be much apprechated.

when u define the array as a class you have to define it with a random figure i.e.
public Temp(0) as Sub_Class
then in the subroutine 'New' for the class "Sub_Class" you call a subroutine called create_X()
Public Test as new Temp_Class(8,1,2)<br />
.....<br />
.....<br />
<br />
Public Class Temp_Class<br />
.....<br />
public Temp(0) as Sub_Class<br />
.....<br />
Private x_Value as integer<br />
Private y_Value as integer<br />
Private z_Value as integer<br />
.....<br />
Public Sub New(ByVal x_val, ByVal y_val, ByVal z_val)<br />
ReDim Temp(Temp_Class.X)<br />
x_value = x_val<br />
y_value = y_val<br />
z_value = z_val<br />
Create_X()<br />
End Sub<br />
....<br />
Public Sub Create_X()<br />
Dim temp_X As New Sub_Class<br />
Dim n As Integer<br />
Public Sub Create_X()<br />
For n = 0 To Temp_Class.X<br />
Me.Sub_Class(n) = temp_X<br />
Next<br />
End Sub<br />
....<br />
....<br />
End Class<br />
<br />
Public Class sub_Class<br />
.....<br />
public Temp2(0) as Sub_Sub_Class<br />
.....<br />
Public Sub New()<br />
ReDim Temp2(Temp_Class.Y)<br />
.....<br />
Create_Y()<br />
End Sub<br />
....<br />
Public Sub Create_Y()<br />
Dim temp_Y As New Sub_Sub_Class<br />
Dim n As Integer<br />
Public Sub Create_Y()<br />
For n = 0 To Temp_Class.Y<br />
Me.Sub_Sub_Class(n) = temp_Y<br />
Next<br />
End Sub<br />
....<br />
....<br />
End Class
this relies on the fact hta default values have been put into the sub_Class and Sub_Sub_Class Properties in the subroutine new() and also relies on the fact the initaliation 'Test' class being called with overload.
if this approach is then taken you are effectivly creating defualt values for thouse classes and by doesing so removes the problem of the computer bringing up Null References
Sorry if this isnt very clear but someone else might be able to write it up more clearly if they can understand what i mean.

I want to connect Webcam to my application. I have made a form i want that as i click the button the image from webcam should be apear in picturebox. Please help me !!!!!!!!!!!!!!!!!
|
|
|
|

This is how i decided to implement it you can mess around with it to how u want it once you have it working.
1) Create a picture box and call it "picCapture"
2) Create a list box and call it "Video_Sources"
3) Create a Button Called "Change_Video_Apply"
4) Create a Buttin Called "Change_Video_Source"
On the Form designer place the Button and List box 'Behind' the Picture box.
Make sure the pic box has a ratio of 4:3 for its Width:Height - stops streching
Copy these into your form class
Place this with you declerations i.e. before subroutines
#Region "Webcam Defines"<br />

I build my Matlab .m file as dll and I'm going to integrate vb.net with this dll. Just, I dont know how to pass an image to that matlab dll? Which data type i should use to declare that image?
Here is the code used in vb.net to call the method in that dll:
Private obj1 As MyMatlabApp.MyClass
obj1 = New MyMatlabApp.MyClass
obj1.methodName(1, objReceivedImage, objSendImage)
Due to the code above:
1 means only 1 object will be returned which is objReceivedImage
objSendImage is the image that i'm going to pass it into the dii for further processing
Anyone who knows about this, pls help me out here. I'm really in fix. Thanks in advance.
